Fluid inventory of the North Hikurangi Subduction Zone from integration of physical properties data and thermodynamic models of metamorphic dehydration
AGU 2024
volcanology, geochemistry and petrology | 13 december 2024
Demian M. Saffer, Andrew Smye, Andrew Gase, Peter ...
Fluids exert a first order control on fault strength, slip behavior, and volatile transport in subduction zones. We investigate the fluid inventory of...

Fluid reservoirs of the Hikurangi Plateau and their implications for subduction processes
AGU 2024
volcanology, geochemistry and petrology | 13 december 2024
Andrew Gase, Nathan L. Bangs, Dan Bassett, Christi...
New Zealand's Hikurangi margin is known for recurring shallow slow slip, numerous forearc seeps, and a productive volcanic arc. Fluids derived from th...

A Predictive Model of the Distribution Coefficient of Boron Desorption: Improving the Use of Boron as a Tracer of Dewatering in Shallow Subduction Complexes
AGU 2024
volcanology, geochemistry and petrology | 12 december 2024
Nicole Ferrie, Demian M. Saffer, Dan Breecker, Bel...
Volatile cycling, earthquake mechanics, and deformation behavior in shallow subduction complexes are modulated by fluid release and migration. Boron (...

Fluid-Induced earthquakes on a 1-meter fault
AGU 2024
seismology | 12 december 2024
David C. Bolton, Luc Lavier, Demian M. Saffer
In the last decade it has been recognized that fluid injection can initiate a spectrum of slip modes, ranging from aseismic creep to elastodynamic rup...

Experimental constraints on the frictional rheology of a slow-moving landslide in California’s Franciscan mélange: Oak Ridge earthflow, Central CA
AGU 2024
mineral and rock physics | 11 december 2024
Samantha Burton, Kaitlin Schaible, Demian M. Saffe...
Understanding the factors that control earthflow failure behavior, e.g. whether motion occurs catastrophically or by transient, slow creep, remains en...

The Role of Frictional Heterogeneity Length Scale in Subduction Megathrust Sliding Behavior
AGU 2024
seismology | 11 december 2024
Rob M. Skarbek, Demian M. Saffer, Heather M. Savag...
Heterogeneity - whether in geometry, stress, or material properties - is widely invoked as a key control on the slip behavior of faults. However, the ...

Hydromechanical Weakening of the Décollement at the Leading Edge of Accretionary Prisms and the Importance of Mean- and Shear-Stress-Induced Overpressures
AGU 2024
volcanology, geochemistry and petrology | 11 december 2024
Maria A. Nikolinakou, Peter B. Flemings, Demian M....
We quantify stress and pore pressure changes in accreting sediments at subduction zones using large-strain evolutionary geomechanical models and reali...

AGU 2024
union sessions | 11 december 2024
Demian M. Saffer
Monitoring and characterization of geohazards represents one core set of challenges that motivate scientific ocean drilling, as articulated in the cur...
